I think we've all been there MaryAnne, so we feel your pain. There is a load of advice online - I put "cutting mat restick" in my search engine (Firefox) and got a whole bunch of hits and some time ago I bought a can of Plottix Freshmat - I think I got it from Graphtec but it was a while ago and I can't find it on their site now but there are other products out there that do the same thing. Some people on here use glue sticks which seem to work well. You could try giving the mat a good wash with some washing up liquid and a gentle scrub with a non stick scourer to clean it but be sure it is perfectly dry before you attempt a restick. Hope it works for you, and by the way thank you for keeping this site going for all these years and I do hope it continues.
